Abstract

PURPOSE:An improved makeup cosmetic having good properties for use, improved finish, and no collapse of color with time, obtained by blending cosmetic with lamellar barium sulfate. CONSTITUTION:Cosmetic such as foundation, eye shadow, cheek rouge, toilet powder, lipstick, etc. consists of powder, an oily component, water, and wax, the cosmetic is blended with 1-90wt% barium sulfate in a lamellar particulate shape, having 0.1-1mu average thickness and 1-30mu average particle diameter. The prepared cosmetic has light spread, good adaptability to the skin, no powdery properties, totally beautiful finish, and especially refreshing feeling in use.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention provides an excellent makeup cosmetic containing plate-shaped barium sulfate, which has good usability and finish, and has little discoloration over time. Regarding.

[Prior Art] Makeup cosmetics such as foundation, eye shadow, rouge, white powder lipstick, etc. usually consist of powder, oil, water, and wax. The powder part is used by mixing extender pigments such as talc, mica, and kaolin with colored pigments and white pigments. Extender pigments blended into cosmetics have a large oil absorption capacity, and as a result, in powdered makeup cosmetics, a problem arises in that the color immediately after makeup is applied differs from the color after the lapse of time. That is, the applied cosmetic gradually absorbs sebum and blends in over time, resulting in a dull color tone. Furthermore, in oil-based and emulsion type makeup cosmetics, the amount of extender pigments that are absorbed is large, which limits the amount of extender pigments that can be blended, resulting in decreased stability and difficulty in the filling process.

[Problems to be Solved by the Invention] As a result of intensive study by the present inventors in order to eliminate the above-mentioned drawbacks of conventional extender pigments and to obtain a makeup cosmetic with excellent usability and finish, By incorporating plate-shaped barium sulfate having a plate-like particle shape and an average particle size of 1 to 30 μm, the problem of disparity was solved, and the present invention was completed.

[Means for Solving the Problems] That is, the present invention achieves good usability and finish by blending barium sulfate with a plate-like particle shape and an average particle size of 1 to 30 μm, and which improves with time. To provide an excellent makeup cosmetic with less color distortion.

Hereinafter, the configuration of the present invention will be explained in detail.

Barium sulfate is conventionally known as precipitated barium sulfate as a raw material for cosmetics, and is approximately spherical particles with a particle size of 0°1 to 1 μm. For this reason, it is inferior to platy clay minerals such as talc and mica in terms of its spreadability, ease of use, and clean finish, so it is mainly used as a body for rake necks.

On the other hand, the barium sulfate used in the present invention has a plate-like shape, preferably has an average thickness of 0.1 to 1 μm, and an average particle size of 1 to 30 μm. If the average thickness is less than 0.1 μm or the average particle size is less than 1 μm, it will not spread or feel good during use, and if the average thickness is more than 1 μm or 30 μm or more, it will feel rough. , the finish is uneven and undesirable.

The amount of barium sulfate added to makeup cosmetics is 1 to 9.
It is 0% by weight. The characteristics of the plate-like barium sulfate applied to the present invention are shown in Table 1 in comparison with conventional barium sulfate and other extender pigments.

*To measure the coefficient of dynamic friction, stick a double-sided adhesive tape on a horizontally placed iron plate, place a sufficient amount of the sample on it, and then apply a load (5 to 100 g) on an aluminum attachment.
/c+m2) and was moved over the sample at a speed of 1°/sec, and the stress was measured using a strain gauge.

**Cardner-Koleman method (oil is linseed oil) Compared to conventional barium sulfate, the barium sulfate of the present invention has a very small dynamic friction coefficient and has good usability, especially slippage. Its value is almost the same as talc and mica. On the other hand, the oil absorption is smaller than conventional barium sulfate, and even smaller than talc or mica. This small amount of oil absorption is related to the difficulty in blending into the skin immediately after makeup is applied, and as a result, it solves one problem with makeup cosmetics: discoloration over time. In addition, the amount of talc, mica, etc. added to oil-based and emulsified makeup cosmetics is naturally limited due to their oil absorption, but using the barium sulfate of the present invention can significantly increase the amount. I was able to do that. As a result, we have achieved an unprecedented feel and finish.
